Chapter 9: Vision

Chapter nine was the easiest chapter I have read so far. Shubin was quick and to the point when talking about eyes. At the beginning of this chapter Shubin descripes the fossil his friend brought him to. It was really cool how he Shubin was able to "see impressions of the whole animal, all the way down to the little shells it ate as its last meal" (149). Shubin takes up a long paragraph explaining how our eyes perceive light and create a picture for us in our brain; but the process happens simultaneously just like our sense of smell. The quick reaction our eyes, ears, or nose have from the external world sending signals to our brains is astonishing. When Shubin turned to explaining Gehring's experiment with the Pax 6, I became a little weirded out and disgusted by the concept of adding an eye some where it did not belong like on a wing. Ever since our eye dissection in the seventh grade, eyes have not been my favorite subject to study. I would rather look into eyes and see "romance, creation, and the windows into the soul" (157). :)
